How Do You Evaluate Peptide Suppliers for Research Use?

[jiyajoj]

Hello everyone.

I'm exploring suppliers and trying to understand how researchers evaluate peptide sources today. What standards do you use when comparing purity data, documentation, and third-party testing? I often see broad claims but little practical guidance.

In the middle of my search, the phrase research peptide catalog keeps coming up, yet I’m unsure how to judge whether a catalog reflects real quality or just marketing. Do you prioritize COAs, synthesis methods, or batch traceability? How important are storage conditions, shipping practices, and customer support for reproducibility?

I’d appreciate insights from labs with experience ordering peptides regularly and avoiding costly mistakes together.
